The mRNA "vaccines" against Covid19 deliver the genetic information that the virus uses to produce the so-called spike protein. This information is encoded in the sequence of ribonucleic acid bases that make up the mRNA molecule.
The spike protein caps the spikes on the Covid19 virus particle and adheres quite specifically to certain of the cells (ACE2 receptors) of the epithelium that lines the lung.
Once attached to an ACE2 receptor, the virus injects its genetic material into the cell. Thereupon, all components of the virus, not just the spike protein, are manufactured by the machinery of the host cell and self-assemble to create a mass of new virus particles.
The information delivered to the cell (any cell in the body) in the form of an mRNA Covid19 "vaccine" is processed by the cell's protein synthetic machinery to produce spike protein. The spike protein is then recognized by the immune system which, in response, produces antibodies that inactivate the spike protein of invading Covid19 virus particles, thereby resisting infection.
Very clever.
Except, among other things, it turns out that the spike protein is responsible, wholly or in part, for the symptoms of Covid19 disease, as just reported in the journal Circulation Research. What that means is that the mRNA vaccines may mitigate against Covid19 infection, or in the event of infection, Covid19 disease. However, it may itself cause lung injury and illness in the complete absence of the virus.
